TOLEDO, OHIO, A CORPORATION OF OHIO V ATOMIZEB Application filed August 21, 1930. Serial No; 476,770,

This invention relates primarily to liquid atomizers of the type used for the spraylng of perfumes, medicinal preparations, and the like.

The object of the invention is the provision of novel and efficient means in an atomizer of this type for sealing it, when not in use, against the evaporation of liquid and escape of fumes from the container, and also against the escape of liquid from the container should it be inverted or placed on its side, thereby particularly adapting it for use by travellers and for carrying in hand bags.

The invention is fully described in the following specification and a preferred embodiment thereof illustrated in the accompanying drawing, in which- Figure 1 is a central vertical section of an atomizer embodying the invention with parts in full and with the sealing parts in closed or sealing relation; and Fig. 2 is a similar fragmentary view thereof with the sealing parts in usable released position.

Referring to the drawing, 1 designates a receptacle for containing the liquid to be sprayed, and 2 a cap or ferrule member which is removably or releasably threaded on the neck 3 of the receptacle and carries a sprayhead 4 of any suitable or well known form. This sprayhead, in the present instance, has a nozzle portion 5 provided with a discharge orifice 6 opening into a chamber 7, which chamber has communication through a passage 8 with a source of air pressure supply, such for instance, as a compression bulb 9, and also has communication through a passage 10 and tube 11 with the interior of the receptacle with its lower end submerged in the liquid contained therein, whereby the discharge of air through the passage 8 and from the orifice 6 will cause liquid to be drawn into the chamber 6 from the receptacle and to be discharged from the nozzle with the air in finely broken up or spray form, as well understood in the art.

The cap or ferrule 2 is provided interiorly with a gasket 12 for seating on the end of the neck 3 and cooperating with the cap to seal the receptacle against the escape of liquid therefrom between the cap and neck.

When the cap is turned sufliciently from its seated position to release the sealing action of the'gasket 12, there is a suflicient leakage of air between the threads of the cap and neck to provide avent for the interior'of'the receptacle when the atomizer is being used.

The liquidtube 11 extends down to near the bottom of the receptacle and is provided at its lower end with a shell or enlargement 13 that is open at its bottom and adapted to receive a gasket 14 of cylindrical form, with the axial passage therethrough in register with the passage through the tube. This gasket has its lower edge'projecting' below the shell 13 and is adaptedto seat-against the bottom of the receptacle,"as shown in Fig. 1, when the cap 2 is screwed home on the receptacle neck to effect a sealing of the cap against the escape of liquid therefrom. The two gaskets 12 and 14 are so relatively spaced that both have sealing coaction with the respective parts of the receptacle at approximately the same time when the cap is turned home on the receptacle neck, as is apparent from the drawing.

It is apparent that to use the atomizer it is only necessary to turn the cap 2 sufficiently to effect an unsealing or release of the engagement of the gaskets 12 and 14 from the respective neck and bottom portions of the receptacle, after which the bulb 9, or other air pressure creating means, may be operated to effect a discharge of the liquid in spray form from the atomizer. This being accomplished, the parts may be again quickly sealed by merely turning the cap 2 home on the receptacle neck, which effects both a sealing of the gasket 12 and the gasket 14 against the coacting parts of the receptacle and prevents any possibility of leakage of liquid from the receptacle, should the receptacle be inverted or placed on its side, and also prevents the escape of fumes and a consequent evaporation of liquid from the receptacle when not in use.

I wish it understood that the invention is not limited to any specific construction, arrangement or form of the parts, as it is capa ble of numerous modifications and changes without departing from the spirit of the claims.

Having thus described my invention, what I claim as new and desire to secure by U. S. Letters Patent is:

1. An atomizer comprising a receptacle having a mouth, a spray head, a mounting for said spray head and closing said mouth, an adjustable connection between said mounting and receptacle, a liquid tube carried b and discharging through said sprayhea and projecting into the receptacle, a gasket carried by said mounting for sealing engage I ment with the rim of said mouth, and a second gasket carried by the inner end of said tube for sealing engagement with the adjacent wall of the receptacle, whereby both gaskets areseated or unseated according to the adjustment of said mounting.

2. An atomizer comprising a receptacle having-a mouth, a spray head, a mounting for saidspray head and closing said month, an adjustable connection between said mounting and receptable, a liquid tube carried by and discharging through said spray-head and projecting into said receptacle, and a gasket carried by. the inner end of said tube for sealing engagement with the adjacent wall of the. receptacle whereby adjustment of said mounting seats or unseats said gasket.

I In testimony whereof .I have hereunto signed my name to this specification.
